Here is the FHSW map timeline sorted by the fronts. It's interesting and can be helpful for creating map lists for events. I have created it based on internet articles, wikipedia, documentary films and own prediction – that are not good sources of historical knowledge, so there can be some mistakes.

Valirisk and for example Sector 318 are fictional maps - [I forgot add (F)] The map traits however could be Zhitomir, since this city was traded back n' forth during the late fall - winter months of 1943, and I set the date of this event. And could you please check the dates of Stalingrad battles, you have better knowledge about this.
